This distribution promises you a very tailored user experience and it does deliver on that promise. The developers provide you with a custom desktop environment and a set of neat programs. And the whole desktop looks simply gorgeous.
elementary does not offer any release date for their stable releases going more with a "it's done when it's done" attitude. Making depending on newer apps a difficulty as well as a poor choice for those that need consistent release schedules for their OS.
The devs of elementary OS feel anyone not paying for their Ubuntu respin are not worthy of using it. Which upset a good bit of people. Obviously the core dev team have issues with their community outreach and PR.
